A.1 Introduction

The standard calibration for your Model 10100AT TRIAD Field Service Kit includes two calibration points
for the Model 96035B ion chamber and one calibration point for the Model 96020C ion chamber. If you
received the standard calibration (which you did unless you requested otherwise), these calibration
factors have been entered into the Model 35050AT Dosimeter. Each calibration factor has been linked to
two Ion Chamber Selection screens, one with air density corrections active, and one with air density
correction inactive. Choosing the proper Ion Chamber Selection screen in the Model 35050AT Dosimeter
ensures that the correct calibration factor for the ion chamber being used is active. Below is a description
of the three default Ion Chamber Selection screens and their meanings.

A.2 Model 96020C (150 cc) Ion Chamber

The standard calibration for the 150 cc Model 96020C ion chamber is performed at the Fluke Biomedical,
Radiation Management Services equivalent of NIST beam quality H60. The calibration factor of your
Model 96020C at this beam quality has been entered into the Model 35050AT Dosimeter and linked to
two Ion Chamber Selection screens which read as follows:

150 cc xxxxx ADC

150 cc xxxxx

150 cc refers to the volume of the Model 96020C ion chamber.

xxxxx is replaced in your selection by the serial number of your Model 96020C.

ADC indicates that air density correction are active.


Both of these selections use the same ion chamber
calibration factor (which can be viewed using the
OPTIONS button). However, using the top
selection results in automatic air density corrections
being applied to your measurements, while the
bottom selection results in no air density correction
being applied.
